Monitoring regional cerebral oxygen saturation throughout the perioperative clinical process is important for successful patient outcomes. Cerebral oximeters based on near-infrared spectroscopy (NIRS) have already been used for monitoring brain oxygenation and hemodynamics to avoid intraoperative ischemic stroke and reduce postoperative cognitive dysfunction. The current devices are all designed to be used as a bedside monitor, limiting their use to situations that center around a hospital bed. There is a current lack of wearable, miniaturized, wireless equipment that can extend brain oxygenation monitoring to motion tasks or tight spaces. We design a head-mounted wearable wireless oxygen saturation monitoring on head (WORTH) band based on NIRS for monitoring regional cerebral oxygen saturation. The band is embedded with a highly integrated central block, which comprises an optical module, a microprocessor unit, a wireless communication module, and a power management module. The performance of the WORTH band is evaluated by a controlled hypoxia experiment and a squat-to-stand experiment. The results confirm that the WORTH band can record cerebral oxygen saturation with an accuracy comparable to that of a clinical monitor and demonstrate that it is also effective during motion tasks.

穿戴式无线实时脑血氧仪可测量区域性脑氧饱和度

在整个围手术期临床过程中监测区域性脑血氧饱和度对于成功的患者预后至关重要。基于近红外光谱仪(NIRS)的脑血氧饱和度仪已用于监测脑氧合和血流动力学,以避免术中缺血性中风并减少术后认知功能障碍。当前的设备均设计为用作床头监视器,将它们的使用限制在以医院病床为中心的情况下。当前缺少可将大脑氧合监测扩展到运动任务或狭窄空间的可穿戴,小型化的无线设备。我们设计了基于NIRS的头戴式(WORTH)头戴式可穿戴无线血氧饱和度监测仪,用于监测区域性脑血氧饱和度。该频段嵌入了高度集成的中央模块,该中央模块包括一个光学模块,一个微处理器单元,一个无线通信模块和一个电源管理模块。WORTH带的性能通过受控的缺氧实验和下蹲实验进行评估。结果证实,WORTH频段可以记录脑氧饱和度,其准确性可与临床监护仪媲美,并证明它在运动任务中也很有效。
